Abstract:
A control apparatus that is connected to at least one image capturing apparatus by wireless communication transmits, by multicast or broadcast via the wireless communication, a command for instructing to start a prescribed operation to each image capturing apparatus, in response to detection of an operation for instructing to start the prescribed operation, and transmits, by unicast via the wireless communication, a command for instructing to end the prescribed operation to each image capturing apparatus, in response to detection of the operation for instructing to end the prescribed operation. Then, the control apparatus confirms a response to transmission of the command for instructing to end the prescribed operation, and retransmits, by unicast, the command to end the prescribed operation to each image capturing apparatus whose response is not confirmed.
